1. nftables - low-level way to manage the firewall on modern distros. It is a replacement for iptables
2. iptables- legacy firewall
3. East to use fronted - manage your nftables or iptables using GUI, CLI, or web fronted. Typical examples are ufw, gufw, Guarddog, FWBuilder, firewalld, firewall-config, etc. Both nftables & IPtables are part of Netfilter. For most users, choosing fronted, such as ufw https://www.cyberciti.biz/faq/how-to-set-up-ufw-firewall-on-ubuntu-24-04-lts-in-5-minutes/ or firewalld https://www.cyberciti.biz/faq/set-up-a-firewall-using-firewalld-on-opensuse-linux/ is recommended
